3 Claims.

This invention relates to an improvementin a cleansing and deodorizing device for water closets, hereinafter referred to as a solution.

One object of the invention is to provide means for discharging a predetermined amount of solution of predetermined strength into the water that is to remain in the bowl of a toilet after flushing.

Another object is to provide means for discharging the solution without diluting the same in-its container.

With the above and other objects in view, as will appear to those skilled in the art from the present disclosure. this invention includes al1 features in the said disclosure which are novel over ,the prior art.

In the accompanying drawings, in which certain modes of carrying out the present invention are shown for illustrative purposes:

Fig. 2 is a iront view, partly in section, of the distributoron a larger scale;

Fig.'3 is a sectional view on the line 3 3 of 1 Fig. 2;

Fig.' 5 is a. perspective view of the vent-tube detached; j i

Fig. 6 is a sectional view of a toilet-tank illustrating a modified form of the distributor;

l Fig. 7 is a side view -partly in section o f the overflow-pipe, showing the. distributor located therein;

Fig. 8 is a vertical sectional view showing the detalls of construction of the distributor located in the overilow-pipe; l

Fig. 9 is a sectional view on the line 9 9 of Fig. 8; and

Fig. 10 is a sectional view on the line IO-I of Fig. 8.

In carrying out my invention, I employ a mixing-chamber I5 adjustably connected tothe lower end i6 of a solution feed-pipe l1, the upper 'end I8 of which is connected to a container i! of any desired form, herein shown as of box-like form, adapted to be suspended in the toilet-tank 2l. The two parts of the feedpipe are connected by acoupling-sleeve 2| to provide for lengthening or shortening the feedpipe, and the lower end il may be held in position by a lock-nut 22. The toilet-tank is provided with the usual inlet-pipe 23, a valve 24, a float to control the valve, and a seat at the upper end of the flush-pipe 21 to receive Application october 7. 193s. serial No. 293,342

a ball-valve 2l adapted to be raised in the usual manner.

Extending into the mixing-chamber il and downward therefrom is a siphon-tuhe 20' having a discharge-end 2l of any desired diameter directed toward the flush-pipe 21 and adjustably connected to the Siphon-tube by a couplingsleeve Il, so as to shorten or. lengthen the `siphon-tube 2! as required. Opening out of the top of the mixing-chamber is a vent-pipe 22 which may be formed with a trap 32. Extending upward through the feed-pipe I1 is an air-pipe 34 which extends into the solution-con- 4tainer I9 to admit air thereto as the solution is drawn oil. Preferably, the upper end l5 of the' pipe 34 is flexible, so as to` bend if the feedtube is shortened.

When the mixing-chamber i5' is empty, the solution will flow down the feed-pipe 'I1 until the lower end of the feed-pipe is submergedv and the flow stopped. Then, as water. rises in the tank 2li, water will pass through the siphon-tube '29' and mix with the solution, the air in the chamber escaping through the vent-pipe 32.

As the amount of solution discharged from the container can 'be determined, no unnecessary waste of solution can take place. The parts are so arranged that when the toilet is flushed, the solution will not be discharged until just before the ball-valve 2l closes the flush-pipe 21, so that the solution mixes with the water that is to remain in the bowl, where it will act as a cleaner, stain-preventive and deodorant.

'I'he water in various sections of the' country differs in mineral content, which is the cause of more or less staining of toilet fixtures by standing'water.- This device can be 'regulated to supply the proper amount of solution to the flushing water to prevent lthe staining of nxtures in any section of the country, the amounts to be determined by the mineral content of the water in that particular section and the condition of the pipes, particularly iron, through which it is supplied.

In many cases toilet tanks are regulated or adjusted to use much less water in the ilushing operation than the type referred to above. Other standard makes vary in the amounts of water remaining in the bowl after flushing.

In the construction of these tanks, a small,

copper refill-pipe is connected with the watersupply check-valve 24, and directed into the overflow-pipe, so that after the ball-valve seats and closes the flush-pipe, and while the tank is refining, sumcient water will he discharged
